SAN ANTONIO -- If the San Antonio Spurs' easier-than-it sounds 113-100 victory over the New Orleans Pelicans on Sunday took on the feel of an afterthought, that was because of what came, well, after the game.

LaMarcus Aldridge scored 22 points in 26 minutes of play and Manu Ginobili added a season-high 17 points off the bench as San Antonio won for the fourth straight game and eight time in the past 10 contests.

Then, the fun began for real as the capacity crowd at the AT&T Center and a gaggle of dignitaries, family members and former teammates were on hand when the Spurs retired the No. 21 jersey of former power forward Tim Duncan in a typically understated ceremony.

Duncan's 19-year career, all with San Antonio, featured five championships and a 1,072-438 regular-season record. The Spurs' .710 winning percentage during Duncan's tenure was the best 19-year stretch in NBA history and was the best in all of the NBA, NFL, NHL and MLB over that time.

Kawhi Leonard added 13 points for San Antonio (22-5) while Tony Parker and Jonathan Simmons had 12 points and Patty Mills scored 11 points for the Spurs. Pau Gasol pulled down a season-high 14 rebounds in 24 minutes of play.

Alexis Ajinca led the Pelicans (9-20) with 16 points while Buddy Hield added 14. Anthony Davis and Langston Galloway scored 12 points each and Tim Frazier had 11 for New Orleans.

The Spurs outrebounded New Orleans 49-37 and went to the free throw line 22 times (making 18) while the Pelicans were just 8 of 14 from the charity stripe.

Asked afterward if his players were amped up in anticipation of the ceremony for Duncan, Spurs coach Gregg Popovich placed his tongue squarely in his cheek when responding.

"I brought my 'I want to play for Timmy Duncan tonight' gauge, and I left it in the locker room," Popovich said. "So I'm not exactly sure how fired up they were. They told me that there's some celebration to come, and I'm going to go -- I'm going to be there."

If a Spurs' victory was a given, no one told New Orleans, who made a bit as late as midway in the second quarter to spoil the first portion of the city-wide party. But the Pelicans couldn't sustain the effort from early on.

"The number one thing is that we just had too many bad possessions," Pelicans coach Alvin Gentry said. "We shortcutted a bunch of things and ended up with 12 or 14 bad possessions and there's no way you can play the Spurs, with the basketball IQ that they have, and make those kinds of mistakes. When we moved the basketball and made cuts, we were fine."

Five points from Ginobili and a 3-pointer from Mills in a 90-second span of the first quarter allowed the Spurs to turn a 19-18 deficit into a 26-19 lead at the 2:58 mark. New Orleans responded with a spurt of its own, tying the game at 26 before a Gasol jumper and a Leonard layup handed San Antonio a 30-26 advantage after 12 minutes.

The Pelicans owned a 44-42 lead at the 6:25 mark of the second quarter after a driving layup by Hield, until San Antonio forged a 9-0 run, capped by a 3-pointer by Danny Green, to sweep past New Orleans and assume a 51-42 advantage. The Spurs led 61-49 at the half.

Aldridge led all scorers with 16 points in the first half while Ginobili hit for 12 and Leonard added 11. Gasol had 12 rebounds in 18 minutes of play before halftime as the Spurs owned a 29-18 edge on the boards.

"It was a game that we had to win and one that we wanted to win badly," Ginobili said. "I guess today we played a little better -- I was certainly more energetic from the two days off we had. But I don't think there was a relationship between the celebration and the type of game we played."

Davis and Ajinca led the Pelicans with 10 points each at intermission, but Davis picked up his third foul with 1:07 to play in the second quarter.

New Orleans got back to within 72-62 on a Hield jumper at the 6:39 mark of the third quarter, but then the Spurs kicked things into another gear again, reeling off an 11-2 run that was highlighted by another Ginobili 3-pointer. Three free throws by Mills with 14.4 seconds to play in the quarter pushed the San Antonio lead to 21 points, 92-71, and allowed the Spurs to play mostly their reserves for the final quarter.

"We didn't play with enough pace and they got open look after open look," Davis said. "Our defense was off tonight. You can't give teams as good as the Spurs open trips to the basket. We have to figure out what kind of team we want to be identified as -- we are running out of time and we have to catch up."
